To all -uhom lit may concern.'

Be it known that I, ToMMIE-OLSEN, a citizen of the Unit-cd States, residing at Iron River, in the county of Iron and State of Michigan, v have invented new and useful Improvements in Rail-Joints, of which the following is a specification.

This invention relates to improvements in rail joints, the object of the invention being to provide a novel construction of the meeting ends of rails, whereby a smooth joint will be provided and hammering upon and depression o' the meeting ends prevented to a material extent, thus prolonging the life of the rails and increasing the strength of the joint.

The referred embodiment of the invention is i lustrated in the accompanying drawing, in whichz- Figure 1 is a side elevation of two united rails embodying my invention. Figs. 2 and 3 are perspective views of the meeting ends of the rails. Fig. 4 is a cross section through the joint. Y

Referring to the drawing, 1 and 2 designate railwa)` rails of ordinary construction, except as to the novel coupling features at the meeting ends, hereinafter described, the webs of vthe rails being provided with the usual holes 3 for the passaffe of bolts 4 cmployed in conjunction with the usual fish plates 5 to couple the ends of the rails together.

In accordance with my invention, the end of one rail, as the rail 1, has its head portion cut away to form a supporting shelf 6 extending inwardly a suitable dlstance from the end of the rail and terminating in a beveled or undercut shoulder 7, formed by the adjacent end of the upper ortion of the head or tread of the rail. Tie other rail 2 is formed at its adjacent end with a tongue S extending longitudinally from its head, said tongue being of sufficient depth to fit over upon the shelf 6 and to bring the tread surface of its head into alinement with the tread surface of the head of the rrail 1. The outer end of the tongue isformed with a beveled face 9 to bear against the beveled surface of the shoulder 7.

In the operation of assembling the rails, the ends of the rails are brought together in the usual manner, and the tongue 8 projects Specification of Letters Patent.

over upon the shelf 6 and rests squarely thereon, thereby reinforcing the rail beyond the joint and electually preventing depression thereof, the beveled end 9 of the tongue tting against the beveled Wall 7 of the shoulder and preventing any tendency of the railA ends to upward movement. from this construction that the coupling por tions will prevent any up or down movement of the meetiner ends, thus avoiding the hammering and depression and wear upon the rails common to those of ordinary construction, and roviding a joint of maximum strength, wliereby the life of the rails will be prolonged to a material extent. Both the vshelf and tongue are coextensive in width with the heads of the rails, thus allowing the rails to be manufactured at a minimum amount of trouble and ex ense.

Having thus described t 1e invention, what is claimed as new, is v Y 1. A rail having an end portion of its head reduced to form an undercut shoulder and a supporting shelf extending longitudinally from said shoulder and having a lane horizontal face, said shelf and shoullder being coextensive in width with the head so as to S0 extend fully to the lateral faces thereof.

2. In a'rail joint, a rail section having an end portion of its head reduced to form an undercut shoulder and a supporting shelf ex` tendine' longitudinally from said shoulder to S5 the end of the rail and having a )lane horizontal face, said shelf and shoiilder being coextensive in Width with the head so as to extend transversely fully to the lateral faces thereof, and a cooperating rail section having an end portion of its head reduced to form :l tongue constituting a longitudinal extension from the upper )ortion of the head, said tongue having a p ane horizontal lower bearing face to rest upon said shelf and a beveled outer end inclined outwardly and down wardly to said face to engage the said undercut shoulder.

3. In a rail joint, a rail sect-ion having the upper portion of its head transversely cut away for a. distance from its end to form a shelf having a plane or unbrokenly-smooth face throughout its length and extending inwardly from the end and terminating in an undercut shoulder, said shelf being coextenl sive in width with the head, and extending It will be seen 60 to the lteral faces thereof, and o'o'operting provided' wvith a. beveled eri-d toV engage said rail section provided with a tongue extendinf7 undercut shoulder. 10v
